I'm not really a fan of closing off virtually the entire world map after a certain point. It's just loses my satisfaction with the world map after that. While I get that there are points of no return and such, but why do it so the world map itself is an effective point of no return? It's just abit eh... cheap. I can see why developers would do it; to create that "end of the world" or "endgame" feeling, but it can really kick you in the teeth.

Linked in with this is the annoyance that is XIII's destruction of virtually all of the Orphan's Cradle. Makes sacrifice farming impossible...
